Description

Technical Field

[0001] This utility model relates to the field of pigment paste technology for mortar, specifically a quantitative addition device for mortar pigment paste. Background Technology

[0002] Yijiao mortar color paste is a functional material made by mixing yijiao mortar base material and color paste in a specific ratio. It combines the adhesion and waterproofing properties of yijiao mortar with the coloring function of color paste, and is widely used in building decoration projects, such as interior and exterior wall coating, waterproof finishing layer construction in bathrooms and kitchens, and grouting after tile installation. Precise control of its dosage directly affects the color consistency and construction quality of the decorative surface. Currently, the quantitative addition of yijiao mortar color paste mostly relies on manual scooping, simple funnel feeding, or traditional mechanical pushing devices. Quantitative addition is achieved by controlling the feeding time or manually observing the scale. These methods are common color paste addition techniques in the industry.

[0003] However, existing quantitative addition technologies suffer from several drawbacks. Traditional devices often have a loose structure, with drive and conveying components being directly connected, resulting in large space requirements and making them unsuitable for confined construction environments. Furthermore, the high viscosity of the mortar pigment slurry makes traditional gravity feeding or intermittent pushing prone to pipe blockage, leading to poor conveying continuity and reduced addition efficiency. The quantitative accuracy is also low; high-speed rotation of rotating components can cause radial sway, resulting in fluctuating delivery volumes, and pigment residue can easily remain in connection gaps, further amplifying errors. The transmission gears are mostly fixed connections, requiring complete replacement after wear, leading to high maintenance costs. Finally, the devices lack versatility, unable to flexibly replace feeding components based on pigment viscosity or dosage requirements, making them unsuitable for diverse construction scenarios. These problems severely restrict the efficiency and quality stability of mortar pigment application, necessitating the design of a quantitative mortar addition device to address these issues. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a quantitative addition device for adhesive mud pigment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative addition device for adhesive mud color paste, comprising a quantitative cylinder, a protective cylinder fixedly connected to the upper part of the quantitative cylinder, a feeding cylinder provided on the right side of the quantitative cylinder, a fixing plate provided on the left side of the feeding cylinder, and the left side of the fixing plate fixedly connected to the right side of the quantitative cylinder. The metering cylinder is rotatably connected to a first rotating rod, a conveying auger is provided on the outside of the first rotating rod, and a first bevel gear is provided on the upper part of the first rotating rod. A fixing block is provided on the rear side of the protective cylinder, and a drive motor is fixedly connected to the rear side of the fixing block. A second rotating rod is fixedly connected to the rotating shaft of the drive motor, and a second bevel gear is provided on the front side of the second rotating rod. The first bevel gear and the second bevel gear are meshed together.

[0006] The upper part of the metering cylinder is fixedly connected to a first limiting seat, the upper part of the first rotating rod is rotatably connected to the inner side of the first limiting seat, the front side of the fixing block is fixedly connected to a second limiting seat, and the rear end of the second rotating rod is rotatably connected to the inner side of the second limiting seat.

[0007] The upper end of the first rotating rod and the front end of the second rotating rod are both provided with mounting grooves. The first bevel gear and the second bevel gear are respectively engaged and connected to the inner side of the corresponding mounting grooves. The upper part of the first bevel gear and the front part of the second bevel gear are both provided with locking bolts.

[0008] A plurality of first fixing bolts are equidistantly arranged on the outer side of the fixing plate. The first fixing bolts are used to fix the whole consisting of the fixing plate and the feeding cylinder to the metering cylinder.

[0009] Several second fixing bolts are equidistantly arranged on the bottom outer side of the protective cylinder. The second fixing bolts are used to fix the bottom of the protective cylinder to the upper part of the metering cylinder.

[0010] An opening is provided on the right side of the metering cylinder, and the discharge port of the feeding cylinder is located at the opening.

[0011] The outer diameter of the conveying auger is the same as the inner diameter of the metering cylinder, and the inner diameter of the feeding cylinder is 1 / 2 of the inner diameter of the metering cylinder.

[0012] This invention provides a device for quantitatively adding colorant to adhesive clay. It has the following beneficial effects: 1. Through the vertical meshing transmission structure of the first and second bevel gears, the lateral power of the drive motor is converted into the vertical rotational power of the first rotating rod, making the overall structure of the device more compact and adaptable to narrow construction environments. Simultaneously, the spiral pushing of the conveying auger avoids the problem of easy clogging of the mortar pigment due to its high viscosity, achieving continuous and stable conveying, improving the device's spatial adaptability and conveying efficiency. Furthermore, the speed of the drive motor can be adjusted through an external control system. Since the pitch of the conveying auger is fixed, the volume of pigment pushed per unit time is proportional to the speed. Operators can precisely control the amount of pigment added by setting the motor speed to meet different mixing ratio requirements. Through the precise fit between the outer diameter of the conveying auger and the inner diameter of the metering cylinder, and the radial constraint of the rotating rod by the first and second limit seats, residual pigment on the inner wall of the metering cylinder can be scraped during rotation, avoiding fluctuations in the conveying volume caused by high-speed shaking of the rotating parts. This also avoids quantitative errors caused by gap residue and shaking, improving the accuracy of pigment addition.

[0013] The first and second bevel gears are detachably connected to the rotating rod by mounting grooves and locking bolts, and the feed cylinder connected to the first fixing bolt is replaceable. After the first and second bevel gears wear out, they only need to be replaced individually. The feed cylinder can be flexibly replaced according to the viscosity of the pigment, which reduces maintenance costs and enhances the versatility of the device. By using the protective cylinder and the second fixing bolt to form a closed structure, the transmission components such as the first and second bevel gears are wrapped inside, avoiding pigment splashing and contamination and the intrusion of external impurities. This avoids the problems of easy jamming and rapid wear of exposed transmission, extends the service life of the device, and improves the working environment. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see the appendix Figures 1-7 A quantitative addition device for adhesive clay pigment includes a metering cylinder 1, a protective cylinder 2 fixedly connected to the upper part of the metering cylinder 1, a feeding cylinder 3 provided on the right side of the metering cylinder 1, a fixing plate 4 provided on the left side of the feeding cylinder 3, and the left side of the fixing plate 4 fixedly connected to the right side of the metering cylinder 2. The metering cylinder 1 is rotatably connected to a first rotating rod 7, a conveying auger 8 is provided on the outside of the first rotating rod 7, and a first bevel gear 9 is provided on the upper part of the first rotating rod 7; A fixing block 5 is provided on the rear side of the protective cylinder 2. A drive motor 6 is fixedly connected to the rear side of the fixing block 5. A second rotating rod 10 is fixedly connected to the rotating shaft of the drive motor 6. A second bevel gear 11 is provided on the front side of the second rotating rod 10. The first bevel gear 9 and the second bevel gear 11 are meshed together.

[0018] Through the vertical meshing transmission of the first bevel gear 9 and the second bevel gear 11, the lateral power of the drive motor 6 is converted into the vertical rotational power of the first rotating rod 7, making the device structure more compact and easier to control; at the same time, the conveying auger 8 rotates synchronously with the first rotating rod 7, and the spiral pushing principle solves the problem of easy clogging of the gluten paste due to its high viscosity. Compared with the traditional gravity feeding method, it achieves continuous and stable conveying, laying the foundation for quantitative addition.

[0019] The upper part of the metering cylinder 1 is fixedly connected to the first limiting seat 12, the upper part of the first rotating rod 7 is rotatably connected to the inner side of the first limiting seat 12, the front side of the fixing block 5 is fixedly connected to the second limiting seat 13, and the rear end of the second rotating rod 10 is rotatably connected to the inner side of the second limiting seat 13.

[0020] The first limiting seat 12 and the second limiting seat 13 respectively form radial constraints on the first rotating rod 7 and the second rotating rod 10, avoiding radial swaying during high-speed rotation, ensuring stable meshing clearance between the first bevel gear 9 and the second bevel gear 11, and reducing gear wear. At the same time, the limiting effect makes the conveying auger 8 rotate more smoothly, avoiding conveying deviation caused by uneven friction with the inner wall of the metering cylinder 1, and improving metering accuracy. The upper end of the first rotating rod 7 and the front end of the second rotating rod 10 are both provided with mounting grooves 14. The first bevel gear 9 and the second bevel gear 11 are respectively engaged and connected to the inner side of the corresponding mounting grooves 14. The upper part of the first bevel gear 9 and the front part of the second bevel gear 11 are both provided with locking bolts 15.

[0021] The mounting groove 14, in conjunction with the locking bolt 15, enables a detachable connection between the bevel gear and the rotating rod. When the bevel gear wears out, it can be replaced individually without replacing the entire rotating rod, reducing maintenance costs. Simultaneously, the snap-fit ​​connection ensures synchronous rotation of the bevel gear and the rotating rod, preventing slippage and transmission lag, and ensuring a linear correspondence between the pigment delivery rate and the motor speed. Several first fixing bolts 16 are equidistantly arranged on the outer side of the fixing plate 4. The first fixing bolts 16 are used to fix the whole consisting of the fixing plate 4 and the feeding cylinder 3 to the metering cylinder 1.

[0022] The first fixing bolts 16 are evenly distributed to ensure that the fixing plate 4 and the metering cylinder 1 are subjected to uniform force, ensuring that the discharge port of the feeding cylinder 3 is tightly fitted with the metering cylinder 1 and preventing the pigment from leaking out of the gaps; the detachable design allows for the replacement of feeding cylinders 3 of different specifications according to the viscosity of the pigment, enhancing the versatility of the device and adapting to diverse production needs. Several second fixing bolts 17 are equidistantly arranged on the bottom outer side of the protective cylinder 2. The second fixing bolts 17 are used to fix the bottom of the protective cylinder 2 to the upper part of the metering cylinder 1.

[0023] The metering cylinder 1 has an opening 18 on its right side, and the discharge port of the feeding cylinder 3 is located at the opening 18.

[0024] The feeding port and the opening 18 are precisely aligned to form a continuous material channel, avoiding the accumulation of pigment residue at the connection point. Residue not only causes quantitative errors but may also solidify and block the channel, ensuring that the pigment directly enters the metering cylinder 1 and improving the smoothness of the conveying.

[0025] The outer diameter of the conveying auger 9 is the same as the inner diameter of the metering cylinder 1, and the inner diameter of the feeding cylinder 3 is 1 / 2 of the inner diameter of the metering cylinder 1.

[0026] The conveying auger 8 fits snugly against the inner wall of the metering cylinder 1. When rotating, it can scrape away residual color paste on the inner wall, avoiding material residue problems caused by the gap between the conveying auger 9 and the cylinder wall of the metering cylinder 1. The reduced diameter design of the feeding cylinder 3 creates pre-pressure before the color paste enters the metering cylinder 1. Combined with the auger pushing, it achieves uniform output of color paste and further improves the metering accuracy.

[0027] Working principle: like Figure 1-7 As shown: First, during the installation phase, multiple fixing structures are required to ensure stability. The fixing plate 4 on the left side of the feeding cylinder 3 is fastened to the right side of the metering cylinder 1 through the first fixing bolts 16 distributed at equal intervals on the outer side, so that the feeding port of the feeding cylinder 3 is precisely aligned with the opening 18 of the metering cylinder 1, forming a sealed material channel to prevent the pigment from leaking from the connection gap during the conveying process. At the same time, the protective cylinder 2 is fixed to the upper part of the metering cylinder 1 through the second fixing bolt 17 at the bottom, enclosing the transmission components such as the first bevel gear 9 and the second bevel gear 11 inside. This not only prevents external dust and impurities from interfering with gear meshing, but also prevents pigment from splashing and contaminating the transmission structure, ensuring cleanliness during long-term operation.

[0028] Secondly, the precise coordination of the transmission system provides the power foundation for quantitative conveying. After the drive motor 6 starts, its shaft drives the second rotating rod 10 to rotate. Since the second bevel gear 11 at the front end of the second rotating rod 10 meshes with the first bevel gear 9 at the upper part of the first rotating rod 7, the power is transmitted in a 90° direction through the bevel gear set, converting the lateral rotational power of the drive motor 6 into the vertical rotational power of the first rotating rod 7, making the structural layout more compact. The first bevel gear 9 and the second bevel gear 11 are respectively engaged on the corresponding rotating rods through the mounting grooves 14 and are axially fixed by the locking bolts 15, ensuring that there is no relative sliding between the gears and the rotating rods, avoiding the conveying deviation caused by transmission slippage. At the same time, the upper part of the first rotating rod 7 is limited by the first limiting seat 12, and the rear end of the second rotating rod 10 is limited by the second limiting seat 13. The first limiting seat 12 and the second limiting seat 13 respectively constrain the radial wobble of the first rotating rod 7 and the second rotating rod 10, ensuring the stability of the bevel gear meshing clearance, reducing transmission wear, and extending the service life of the equipment.

[0029] Furthermore, the precise design of the conveying structure ensures quantitative accuracy. The outer diameter of the conveying auger 8 on the outside of the first rotating rod 7 is perfectly matched with the inner diameter of the metering cylinder 1. When the auger rotates with the rotating rod, its blades can scrape against the inner wall of the metering cylinder 1, completely pushing the color paste entering the metering cylinder 1 and avoiding quantitative errors caused by residue accumulation. The inner diameter of the feeding cylinder 3 is designed to be 1 / 2 of the inner diameter of the metering cylinder 1, which not only ensures that the color paste can flow smoothly from the feeding cylinder 3 into the metering cylinder 1, but also creates a certain pre-pressure for the color paste before entering the metering cylinder 1 through the diameter reduction design. Combined with the continuous pushing of the auger, the uniform and stable output of the color paste is achieved.

[0030] Finally, during the entire operation, the speed of the drive motor 6 can be adjusted by the external control system. Since the pitch of the conveying auger 8 is fixed, the volume of pigment pushed per unit time is proportional to the speed. The operator can precisely control the amount of pigment added by setting the motor speed to meet different mixing ratio requirements. At the same time, the multiple fixing structures and limit design ensure that the equipment does not loosen or deviate under high-frequency operation, further improving the stability and reliability of quantitative addition.

[0031] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
